A study published by Teerasarntipan et al in the World Journal of Gastroenterology provides valuable insights into prognostic scoring for acute liver failure and in-hospital mortality in patients with dengue-induced severe hepatitis. Their findings validate the model for end-stage liver disease score as the most reliable predictor while demonstrating the utility of the simpler Easy Albumin-Bilirubin score. Despite these findings, current prognostic models face limitations in real-world clinical applications. This letter discusses the strengths and weaknesses of current prognostic models, proposes future directions for improving prognostic accuracy and clinical implementations. This letter also broadens the horizons of prognostic models for liver dysfunction caused by other viral infections.
